Local doctor Liam Cavanagh realises that something isn't right with Charity, but when Mack raises fresh concerns, she dismisses them.
Once Charity is alone again, she reaches for something to protect herself as she doesn't feel safe.
During a night terror, Charity then leaves Mack gravely injured, believing that she's acting in self-defence.
Emma Atkins, who plays Charity, told us: "She's suffering from what I can only describe as severe sleep deprivation.

"I spoke to a psychologist about this and sleep deprivation can be a terrible form of mental torture. You're not seeing the world as a balanced human being, you're seeing it from a very different perspective.
"Everything feels hyper. She's hyper-vigilant, she's hyper-alert. Her vulnerability levels are through the roof. She's scared of everything and so she lies there trying to sleep and when she finally falls asleep, she suffers night terrors which are really disturbing.
"She's seeing Harry and she's hearing and seeing the gun go off. It's creating this awful sense of fear that she's never experienced before."

Emma continued: "When Charity finally falls asleep, she's disturbed from the noise of a car and then a bin being knocked over and when she hears this, she assumes Harry or Harry's gang is coming for her. She fears vengeance will be done.
"Charity is constantly locking the doors and when she falls asleep on the sofa, she gets woken up by the car and she runs to the drawer to find any kind of self defence.
"Her mind plays tricks on her and Mackenzie lets himself into the house and she's having a night terror. He walks round the sofa, realises that she's dreaming and gently touches her leg.
"Charity immediately lashes out thinking it's something more sinister when in actual fact it's just Mackenzie. And this is when all hell breaks loose and she lashes out at him, leaving him gravely injured."
